L UG-STRAP HOLDER FOR LOOMS.

SPECIFICATION formingpart of Letters Patent No. 760,972, dated May 24, 1904.

Application filed February 18, 1904. Serial No. 194,130. (No model.)

To aZZ whom it may concern.-

Be it known that 1, WILLIAM DONNER, a citizen of the United States, residing at Dubuque,

in the county of Dubuque and State of Iowa,

This invention has for its object the production of. a strong, efficient, and cheap device to hold the lug-strap in proper position on the picker-stick in a loom, the holder being so constructed and arranged that it can be adjusted along the picker-stick without the use of bolts or screws entering the same.

Probably the simplest and most common form of holder isa loop of leather secured to the outer edge of the picker-stick by a bolt or screw, the lug-strap passing around the sticl and through the loop. 7 I

When any change is necessary in the position of the holder, the fastening must be taken out and inserted higher up or lower down in the picker-stick, as the case may be, the holes so made weakening the stick and being a prolific cause of breakage.

In my present invention the holder comprises a body portion which embraces the picker-stick and is clampedv thereon at the desired height, obviating the formation of holes in the stick and in no wise decreasing its strength.

The various novel features of my invention will be described in the subjoined specification and particularly pointed out in the following claims.

Figure 1 is a front elevation of a portion of the picker-stick of a loom, the lug-strap, and a lug-strap holder embodying one form of my invention. Fig. 2 is an enlarged outer end View of the device shown in Fig. 1. Fig. 3 is an inner end view thereof. Fig. 4-is a sectional detail on the line 4 4, Fig. 2, the pickerstick being shown in elevation. Fig. 5 is a side elevation of a modified form of the lugstrap holder. Fig. 6 is a View of the body portion thereof opened out flat. Fig. 7 is an outer end view of the modification shown in Fig. 5,

and Fig. 8 is a perspective detail of the clamping member to be described.

Referring to Fig. 1, the picker-stick P, shoe S, on which it rocks, the picking-arm A, and lug-strap M may be and are all of usual or well-known construction.

In accordance with my invention the body of the holder is made of metal, preferably malleable iron, about one-sixteenth of an inch in thickness bent into the form of an elongated U, the bend 1 being increased in width, the narrower extensions 2 being of sufiicient length to project beyond the picker -stick when the holder is in position thereon. The bend 1 has on its inner face a thickened portion or boss 3, Fig. 4, provided with a threaded hole to receive a screw-bolt 4, the inner end of the latter pressing against a pronged holding device or catch, shown as a metal plate 5, having its end bent over at 6 and notched or pronged to enter the adjacent edge of the picker-stick. A headed stud 7 is passed through the ends of the extensions 2 of the body, and a locking-nut 8-is screwed onto the threaded end of the stud, as shown clearly in Figs. 2 and 3. Between the extensions a clamping-cam 9 is rotatably mounted 'onthe stud, said cam being hollowed out, as sh'owii in Fig. 4, to decrease its weight. The lower part of the cam has a' lateral extension 10, up turned at its outer end at 11 to clear the body of the holder and providing a finger-piece by which the cam can be set in clamping position;

As clearly shown in Fig. 4, the plate 5 engages the inner edge of the pickerstick, the latter passing between the sides of the U- shaped body, with the cam opposite the outer edge of the stick, and in said figure I have shown a second pronged or toothed plate 12, having teeth 13 to enter the wood of the stick, the cam acting upon the back of the plate 12. When the cam isturned in the direction of arrow 14, Fig. 4, it presses the plate 12 against the outer edge of the picker-stick and acting through thesides of the body of the holder causes the screw-bolt 4 to press the pronged plate 5 against the inner edge of the stick, securely clamping the holder in place. The pronged plates by their engagement with the picker-stick prevent the holder from becoming displaced accidentally. When the cam is set, the nut 8 is tightened, compressing the free ends of the body extensions 2 tightly against the ends of the cam, so that the latter cannot work loose. One of the extensions 2 has a depending portion bent to form an upright loop 15, through which one side of the lug-strap M is passed, the strap being thereby held in desired position with relation to the picker-stick. The top of the loop 15 is shown in Fig. 3 as bent in and downward at 16 to prevent lifting of the lug-strap, while the spring of the loop permits ready positioning of the strap therein.

By means of the screw-bolt 1 the holder is adjusted to varying widths of picker-stick.

The construction is simple and cheap to manufacture, as the body of the holder can be stamped out readily and the clamping-cam and finger-piece or handle 10 11 can be made as a casting.

If desired, a wrench can be applied to the finger-piece in setting up the 0am.

The prongs of the plates 5 and 12 do not penetrate the wood of the stick far enough to injure or weaken it in any way.

In Figs. 5 to 8. I have shown a modified form of holder, and, referring first to Fig. 6, the body consists of a substantially rectangular portion 17 toothed at its upper and lower edges, as at 18. Extensions 19 extend from each side of the portion 17 decreasing in width outwardly and terminating in depending portions 20. Holes 21 are punched in the extremities of the extensions, and it will be seen that they and the depending portions 20 are symmetrical at each side of the central portion 17.

When the body is stamped out fl-shaped, ears 22 are cut out in the extensions for a purpose to be described.

The body is bent along the dotted lines 17 to bring the extensions 19 into parallelism, and the toothed edges 18 are bent over and inward, as in Fig. 5, forming prongs which enter the edge of the picker-stick.

The cars 22 are bent down at the outer faces of the extensions on the dotted lines 23, Fig. 6, into the position shown in Fig. 5, and the lower ends of the depending portions 20 are bent outward and upward, as at 24, along the lines 24?, Fig. 6.

Aclamping-cam 25 is eccentrically mounted between the extensions 19 on abolt 26, passed through the holes 21 and provided with a setnut 27.

Referring to Fig. 8, the cam has at one end a polygonal extension 28, by which the cam can be setup, using a thin flat wrench or spanner, and then said cam is locked by tightening the set-nut 27. In this construction I obviate the use of separate pronged holdingcatches, the prongs or teeth 18 engaging one end of the picker-stick, while its other edge is directly engaged by the cam 25, as is clearly shown in Fig. 5.

The lug-strap M (shown in dotted lines, Fig. 5) is vertically supported in the upturned loops 24 at each side of the picker-stick and prevented from lifting by the overhanging cars 22.

My invention is not restricted to the precise construction herein shown and described, as the same may be modified or changed in various particulars without departing from the spirit and scope of my invention.
